One more thing I noticed on the drive home. The heater went to cold once I got up to speed. I notice it has a heater control valve, do these go bad like older BMW 5 series, whereas at a stop you have heat, but cruising at speed you don't?

Also-, my temp gauge never even makes it to the first line. There is what looks to be a temp sensor on the front of the engine, passengers side, but all it is mounted to is a metal bracket, and this is not hooked up? There is a wire there for it, but the other end of that wire is not hooked up either, and I cannot for the life of me see what it could be hooked to. Any idea's? Hopefully I'll be able to identify that part tomorrow with the service manual I pick up.
